    Melancholia… Quoting from various references, Melancholia is a drama full of humanity where math and academic material is added to the romance.

    Being a nonmathematician, I learn the other perspective about math. Melancholia tells stories about mathematics in a closer view of our everyday lives, such as unanswered problems. I can feel beautiful and deep conversations about math. This drama is not only about solving and proving math problems, but also using the meaning of mathematics as a metaphor in the journey of life and love. This drama portrays about parenting, educating, toxic parents, psychological trauma, unbridled ambitions, academic and corruption scandal, and of course about the romance of the two main casts.

    I respect how the scriptwriter develops the relationship and romances of the two main casts: teacher (Ji Yoon Su) and high school student (Paik Seung Yu).

    Ji Yoon Su is a mathematician who loves math and a teacher who cares deeply about her students equally. Ji Yoon Su discovers Paik Seung Yu, who is similar to her: loves math and sees the world through a mathematical point of view. Paik Seung Yu actually a math genius, but has the worst grades in school. Trauma faced due to past incident made him seems to have given up on everything and had stopped caring about math and people. Ji Yoon Su is the only adult who truly peers into his heart and cares for him. She also helps him to overcome his trauma and return his true identity. Seung Yu feels strangely attracted to Yoon Su.

    I think at this age, it is possible for Seung Yu finds his first love or puppy love or even true love to his teacher, Ji Yoon Su. It is common and might be happens a lot around the world: students falling in love with their teachers. Ji Yoon Su clearly draws a line as a teacher. She gently pushes him away after Paik Seung Yu confesses his feelings to her. Ji Yoon Su refuses a gift of Seung Yu’s sign of love. Ji Yoon Su shows the mature and grown-up way of handling the relationship between herself and her student. This feeling only one-sided love. There’s no relationship between them in school days.

    Ji Yoon Su and Paik Seung Yu seem to have “close interactions” while preparing for the International Math Olympic. It gives rise to controversy and causes “discomfort” for some viewers. However, I think this drama tries to highlight her enthusiasm, her spirit, her passions, her deep cares as a teacher to encourage her student, but at the other side, her acts may be look reckless and naïve. It doesn’t please anyone else and give rise to rumor of the two; rumor actually spread to cover academic and corruption scandal that almost exposed. The rumor ruined her career. That’s what makes this drama emotional and trigger the conflicts.

    The romances of the two actually begins four years later. An adult Seung Yu, who now became a famous mathematician, finally reunited with Ji Yoon Su, who disappeared for 4 years after the tragedy. Seung Yu is trying so persistent to get closer again to Ji Yoon Su and help her to prove her innocence. The two gradually grow closer. And at this phase, Ji Yoon Su finally realized that he had fallen in love with Seung Yu. It doesn’t matter for age-gap. They are both adults, single, and love each other. Afterwards, the two get involved to expose the truth and academic scandal and corruption that ruined her four years ago.

    There’s a great teacher behind a great student. Thanks to our pretty and beloved teacher, Lim Soo Jung. You portrayed this character perfectly. You are really fit on it. I wonder no one can portrays it as well as you. I love your voice and your shady eyes. Lee Doo Hyun, your brilliant acting skills do show that you really deserve to win awards for best actor this year. Congratulations!

    I have been watching ep 1-11. I enjoy watching this drama and I’m in love with the storyline, Airing at the end of this year, thank you for filling our hearts with this beautiful and heart-warming drama, beautiful osts, beautiful cinematography. Wishing this drama has a HAPPY ENDING; They deserve to be together and happy.

    Thanks to scriptwriter, casts, director and all production teams.

    Much love and peaces…

  4. 4 : Maria Sophina Irewati Says:

    This is a good drama, which tells a different story than usual. Each episode is interesting to watch. But unfortunately, this drama ends with a romantic atmosphere that seems forced. If Seung Yoo and Yoon Soo remain close friends, it will be even better and elegant. But anyway, thanks for this great series. Thank you for the great chemistry between all the players. Success and good health to you all.
